A year ago, in front of Sava, an unknown person killed his fiancee Lena. The investigation did not find the perpetrators in this case. On the anniversary of Elena's death, Sava's partner Vadim Orlov asks a colleague to swap shifts with him because his child is sick. Before Sava arrived at the service, a message was received that an unknown person had killed a major St. Petersburg crime boss, Alexei Chukhonets. The search for the killer leads Savostyanov to businessman Boris Komarovsky, nicknamed Ladoga, who most likely hired the killer and "ordered" Chukhonets. And the "executor" of Komarovsky's order was a well-known liquidator in criminal circles named Tablet. And now Save needs to find Tablet.
